John Carpenter's directorial debut is a low-budget, sci-fi satire which focuses on a group of scientists whose mission is to destroy unstable planets. During their journey, they battle their alien mascot (who closely resembles a walking beach ball), as well as a "sensitive" and intelligent bombing device which starts to question the meaning of its existence. Enjoyable early feature from John "Halloween" Carpenter and Dan "Aliens" O'Bannon. Fun, weird, and unpredictable.
